Celebrating Cassini…Live!

More than 1,100 fans of the just-completed 20-year mission to Saturn joined us for a live tribute. The Planetary Society’s Mat Kaplan and KPCC Science Reporter Jacob Margolis welcomed mission leaders and the Society’s Emily Lakdawalla to Caltech’s Beckman Auditorium stage. You’ll also hear a musical tribute to Cassini’s Grand Finale. Mat and Bruce Betts add space limited edition space art to the prize package in the What’s Up space trivia contest.
